upright; wall 11; t'Ihe vaporizer chamber is thus conveniently supported and provides one of. the bounding walls of the combustion chamber 17. The top plate 16 is provided With-a handhole closed by a cover plate 18. =Surrounding said combustion chamber are twoindependent annular i chambers 20-, 21

wvhich are formed between: three annular sheet metal-walls or shells 22, 23, 24-Which surround .the said chamber and constitute jackets therefoix. The saidchambers are 7 closed at-the upper ends by an'annular top' plate 25 which supports the vaporizer. The innerchamber 20 is closed at itslower end by a .plate 26 which extends entirely across the bottom ofthe chamber, as shown in Fig.

3. The outer chamber 21 is closed by a simllar plate 27, which, however-,is spaced from the plate 26' to provide a space or passage 28 which connects the vertical portions of the a, fuel I for explosive chamber-[21, {the whole constituting an exit passage for the products oficombustion which are generated in the a combustion chamber 17; the said combustion chamber communicating with the exit passage (28, 21)

I through the opening31 at the bottom thereof.. The products of combustion are finally discharged througha vent or smoke pipe 32 which communicates with the annular portion of the passage Eat a point remote from the opening 31. a In order 'to prevent the products of combustion from passing directly to the vent pipethe lower or .bottom parteof the exit passage is closed by a barrier nplate 33 arranged between. the opening 31 12, and is closed at its top by and the vent pipe, and baffle plates 34 are arranged in the vertical part-of the exit passage asshown in Figs. 3 and .4, so as-to diall partscof the .exit passage thusformed. The inner annularchamber 20 constitutes a preheating chamber for the-air that isto 'be mixed with the oil. prior, to-the delivery of .of the products, of combustion in the outer or surrounding exit passage 21.

All .under pressure s del vered to the preheating chamber 2.0. through the pipe 36 and fills all parts of the chamber and ts temperatureris ther 'n raised. The preheated air is -taken,. t rom aid 7 chamber at the opposite side ofthestructure and at the top thereof nished thereto in a manner now to be described.

Oil under suitable pressure is supplied to the producer through a pipe fliwhlch leads into a coil 43 that is submerged in water in the vaporizer chamber 13. The oil is preheated, in its passage through said coil to facilitate its admixture with the commingled air and vapor at the injector device 39 prior to the admission of the mixture into the generator 45, which, as herein shown,.has the form of a coil located in the combustionchamber 17. The oil is led from the preheating coil 43 through a pipe 46 to the injector device 39. The said injector device may be of any Well known or preferred type. As herein shown", it comprises a pipe 47 whichv extends through a suitable stuffing box 48 formed in a cast metal plate 49 bolted to the outer shell 24 and through said shell, the shell 23, the plate 50 between the shells 22, 23, and through the shell 22 and the upright wall 11, and is connected at its inner end to the receiving end of the generator coil 45. The said pipe 47 is ofi'set at its outer end to receive a smaller oil pipe 52 thatextends a distance into the larger pipe 47. The air pipe 38 and ,the oil pipe 46 are connected to the pipes 47 and 52, respectively, and are provided with suitable valves 53, 54 to regulate the proportion of the mixture of the gas making constituents. The stems of the said valves may be geared together, as by the gears 55, 56, whereby both valves ma; be simultaneously adjusted, as by means 0 the lever arm '57 to thereby maintain a prede-' termined or tixedproportion of the gas making constituents while providing means for varying the supply of a predetermined mixture to the generator coil.

The gas produced in the generator coil is carried away therefrom by the exit pipe which, may lead to any suitable point for the disposal of the gas, as to a storage tank if the gas is to be stored, or tea point for immediate consumption of gas. The gas may pass from the pipe 60 to its point of use, through a scrubber and a purifier, in a well known manner. In order to adjust the supply of gas making constituents to the demands upon the gas I may provide the following regulating mechanism: Connected to the gas outlet pipe (30 is a pipe 61 which discharges at its upper end into a-holder 62, the

bell 63 of which dips into a bodg of water in the holder to seal the same. aid bell is connected, as by means of the counterbalanced cable 64, trained about pulleys 65, with-the adjustin arm 57 of the injector device 39 to provi e means for automatically regulating the supply of the gas making constituents to the gas generator coil to correspond with the demand upon the resultant of pipe 65, 66 arrangedend toend' and extending through the metal plates 49 and 50.

The pipe section 65 is inserted outwardly.

through an opening injthe ,waI 1 1 ana extends into and has screw-threaded engagement with the intermediate plate- 50. The pipe section 66 is fitted into an opening in the neck 67 of the outer plat e 49 and extends inwardly into andhas screw-threaded engagement with the said opening in the plate 5O. This arrangement constitutes a simple, convenient and economical mode of forming an opening through the wall of the producer. The saidopening is closed at its outer end by a cover plate. ordoor 68 which is hinged at one side at 70 to the outer plat 49 to swing upwardly away from the opening, andis provided at the opposite side with a hook to engage over a stud 71 fittjed in the saidplate49.

The said opening'thus termed isprovided for introducing into the combustion chamber fuel for preliminarily heating the Walls of the combustion chamber v and the generator coil to a temperature required to generate gas in the coil u on the delivery ofth'e fuel constituents to 518" coil. This preliminary heating maybe effected by means of a burner or torch 73 of any suitable construction which may be supported in anyjsuitable manner, not herein shown, in position todirect the fuel constituents therefrom through the side'opening or passagelof the pro ucer to the combustion chamber 17 when-t the chamber and the. generator coil have been raised to the required temperature the 'valves of the injector 39 are opened to admit the oil and mixture of air and vaporjnto ,the generator coil, where it is .actedu on, not only by the exteriorly impressed:v eat. but also by the heat due to partial combustion of the gas making constituents toconvert the v same into a fixed combustible gas. I j

When using certain grades of oil as the hydro-carbon constituent of thegas, the partial combustion of the 'oil within the generator'eoil may be sufficient to maintain the heat required to convert the-constituents into gas. For other grades of oil, it is necessary to maintain a supplemental combustion for ,instance gas may constituents I theproper burnlng mixture within the com; a

may be: taken from the preheating chamber,

when heated air aloneis desired, or may be taken from thewair vapor steam is to be admitted to the combustion chamber. As herein shown, an auxiliary pipe leads upwardly from the gas exit pipe=60 andiis directed through suitable 0 enings in the plates 49, ,50 and the wall o the GOIl'lbllStlOIl chamber to deliver gas to'the chamber 17. Anauxiliary air pipe 77 may be led downwardly. from the, air and vapor pipe38. and, as ".shown in Figs. 1, 2 and-4, extends throughan opening in the through the side opening sections 65,- 66, with its inner end closely adjacent to the discharge end of the auxiliary gas supplypipe 75. Said auxiliary gasaud air. pipes with suitable regulatingvalves 79, 80 re spectively, to regulate the flow of the fuel therethrou-gh so asto produce bastion chamber 17. In FigQG is shown an the preheating chamber 20. ever, thefuel constituents to maintain such supplemental combustion may be taken from sources exterior. to the .producer, but it is advantageous to employ for this purpose heated fuel constituents- The generator coil, herein shown, comof superposed banks of rener on thewalls of the retort and connected from end to end of the coil to constitute a resultant gas as the same flows through the coil. TlllS constructlon ot the 0011 provides means .for subjecting the gas making constituents to a maximum area of heating surface The turns of the coil are so arranged as alternate compression and expansion during thelr passage through the coil so as to therea by result ina complete admixture of the gas a making constituents to bring all parts thereof in contactwvith the heated walls'of the coil. andprevent the formation of relatively cool conesmt the .nlateilal II) the ,(iOll such as bank of turns 0 diameter, and

scribed will be apparent from therforegoing,

briefly recapitulated asfollows:

Air is delivered through the pipe 36 and oil is delivered through-thepipe 42 under predetermined pressures .from suitable sources of supply. Air in passing through the preheating chamber 20.absorbs:some of the heat given off by radiation .trom the N combustion chamber, and from the products,

of combustion which escape through the chamber or passage 21. The preheatedi air.

1 upon entering the vaporizer chamber takes up a; percentage of water, due to the pres-. sure of the air and the temperature of same. The oil. in passing through the preheating coil 43 is raised' in temperature by heat from the water surrounding thecoil. vThe preheated oil and mixture of air and vapor are intermingled at the nozzle of the injector 39 and are forced under their pressures into the generator coil, which coil-and the Walls of the combustionchamber have been'preof the gas. --Supplemental combustion is effected.- and maintained in,the combustion chamber. 17, if requirerhby gas and air delivered through.v the pipes 75 and a The products of this supplemental combustion, as well as the prelnnlnary combustion of viously heated by the burner 73.

An advantage of the construction, aside from those hereinbefore enumerated, is found in its compactness. Another advantage is thatpractically ll the material used in the construction of Hi producer is standard, material -of colylm ce. For instance,
